After I published D3 bot here long time ago, now I bring a new bot for Hearthstone , it's called HearthRanger.
Now HearthRanger is in open beta phase, it's free of use for everyone, it has outstanding A.I. performance compare to other bots, you'll love it if you used other bots before.
It's very easy to use, you can download it from our forum:
Download Hearthstone Bot - HearthRanger - News And Updates And Download (HS) - Rush4X Forum
And it's fully customizable :
